I found that a really interesting webpage.

I have been on "ghost hunts" - over night vigils in old castles / museums. I am not sure what I believe, but they have been interesting experiences.

Have only had one night when something happened that I couldn't explain. A bright flash of light from a corner of a room where there was not electricity and several people saw it.

My mother and father once saw an orb come out of the TV - they both saw it bounce along the floor and both heard it hit the door at the other end of the room.

Maybe they are just random collections of energy, like static, I don't know - but still fascinating.
